• This feature is one that allows operation of the whole system from less than 3V.
• The circuit contains its own adjustable reference and accurate 10-step voltage divider.
• The low-bias-current input buffer accepts signals down to ground, or V −, yet needs no protection against inputs of 35V above or below ground.
• The buffer drives 10 individual comparators referenced to the precision divider. Indication non-linearity can thus be held typically to ½%, even over a wide temperature range

FEATURES:

• Drives LEDs, LCDs or Vacuum Fluorescents
• Bar or Dot Display Mode Externally Selectable by User
• Expandable to Displays of 100 Steps
• Internal Voltage Reference from 1.2V to 12V
• Operates with Single Supply of Less than 3V
• Inputs Operate Down to Ground
• Output Current Programmable from 2 mA to 30mA
• No Multiplex Switching or Interaction Between Outputs
• Input Withstands ±35V without Damage or False Outputs
